North Korea has launched multiple surface-to-ship missiles today. South Korea's Defence ministry said North Korea today fired multiple unidentified projectiles, assumed to be surface-to-ship missiles from the vicinity of Wonsan, Gangwon Province. <br/><br/>It would be the fourth missile test by the nuclear-armed regime in less than five weeks, as Pyongyang continues to defy UN warnings and US threats of possible military action. Early last month, the North test-fired its longest-range ballistic missile yet tested, in a bid to bring the US mainland within reach. <br/><br/>Pyongyance also carried out two atomic tests and dozens of missile launches since the beginning of last year.<br/><br/>The UN Security Council last Friday unanimously adopted a US-drafted resolution imposing new targeted sanctions on a handful of North Korean officials and entities, in response to a series of ballistic missile tests this year that are banned under UN resolutions.
